    cost of each bag of popcorn = $7

    and cost of each drink = $6.75

    Explanation:

    given data

    Mason spends a total = $69.75

    drink = 9 drinks

    bag = 1

    Cooper spends a total = $68.25

    drink = 3 drinks

    bag = 7

    solution

    we consider here

    cost of each bag of popcorn = x

    and cost of each drink = y

    so we can write equation as

    9x + 1y = 69.75 ... 1

    3x + 7y = 68.25 ... 2

    we will Solving the system of equation and we get

    x = $7

    y = $6.75

    so cost of each bag of popcorn = $7

    and cost of each drink = $6.75
